1.1 Function and configuration
VEGAKON compact level switches detect levels of
conductive liquids.
Annular electrode (3-elements), oscillator and power
supply form one unit. The modular construction of the
oscillator allows installation in virtually any application..
When the electrode is covered by the product, small
alternating currents (< 1 mA) flow from the meas.
electrode to the reference and neutralization electrode.

Fig. 1 Annular electrode
These alternating currents are measured in respect to
their amplitude and phase position and processed into
a switching signal.
Acc. to the oscillator (module) a relay gets energized
or de-energized or the transistor output is conductive
or blocked (mode A or B) see "4.1 Indicating and
operating elements".
Product build-up is eliminated via the neutralization
electrode; the conductivity is measured and the switch
point sensitivity is automatically adjusted.
VEGAKON can be therefore used for reliable detection
of products over a very wide conductivity and viscosity
range.
